Abstract OBJECTIVES The use of endoscopic vein harvesting in patients undergoing coronary artery bypass grafting is increasing, often using bedside mapping. However, data on the predictive value of great saphenous vein (GSV) mapping are scarce. This study assessed whether preoperative mapping could predict final conduit diameter. METHODS A prospective registry was created that included 251 patients. Saphenous vein mapping was performed prior to endoscopic vein harvesting at 3 predetermined sites. After harvesting and preparing the GSV, the outer diameters were measured. Appropriate graft size was defined as an outer diameter between 3 and 6 mm. RESULTS A total of 753 GSV segments were analysed. The average mapping diameter was 3.2 ± 0.7 mm. The harvested GSV had a mean diameter of 4.7 ± 0.8 mm. Mapping diameters were significantly positively correlated with actual GSV diameters (correlation coefficient, 0.47; P < 0.001). If the preoperative mapping diameters were between 1.5 and 5 mm, 96.6% of the GSVs had suitable dimensions after endoscopic vein harvesting. CONCLUSIONS Preoperative bedside mapping moderately predicts final GSV size after endoscopic harvesting but could not detect unsuitable vein segments. However, the majority of endoscopically harvested GSVs had diameters suitable to be used as coronary bypass grafts.

Aim. To compare patency of aortocoronary bypass grafts in remote period after endoscopic and conventional (open) great saphenous vein harvesting. To analyze the patency of aortocoronary bypass grafts after endoscopic vein harvesting from calf and thigh.Methods. The study involved 170 patients who underwent elective isolated coronary artery bypass grafting. Treatment results were evaluated in two prospectively formed groups: endoscopic (85 patients) and open (85 people) vein harvesting. Endoscopic vein harvesting was performed both from the calf and from the thigh through popliteal access using endoscopic system Vasoview 6.0. Patency of autovenous aortocoronary grafts was studied in 2.6±1.17 years after surgery using 64-slice contrast-enhanced MDCT or traditional angiography. Angiographic follow-up covered 76 patients with endoscopic vein harvesting and 79 patients with open vein harvesting.Results. The studied groups did not differ in the frequency of detection of occluded, stenotic and fully patent autovenous aortocoronary bypass grafts (p=0.841). In endoscopic vein harvesting group frequency of autovenous aortocoronary bypass grafts occlusion was 25.7%, in the group of open vein harvesting - 25.1% (p=0.984). There was no difference in the patency of internal thoracic artery grafts to the left anterior descending artery (p=0.227), and freedom from adverse cardiac events (p=0.342). Occlusion of autovenous grafts after endoscopic harvesting from the calf developed less frequently than after endoscopic harvesting from the thigh (15.1 vs. 34.6%; p=0.013). Grafts after endoscopic harvesting in the knee region occluded most often (41.9%). Patency of aortocoronary bypass grafts after open vein harvesting was not dependent on the area of the vein harvesting (p=0.900).Conclusion. Endoscopic vein harvesting does not compromise the patency of aortocoronary bypass graft and does not increase the risk of its occlusion; endoscopic harvesting of the veins from the calf improves indicators of aortocoronary grafts patency and reduces the risk of graft failure (odds ratio 0.3; 95% confidence interval 0.14-0.8; p = 0.013).

Vein Harvesting

Background: Coronary artery bypass graft Surgery is an established method of myocardial revascularization. Great saphenous vein is the conduit of choice for all cardiac surgeons. Objective: To compare the effect of great saphenous vein harvesting on lower limb such as swelling, pain, discharge with diabetic and non diabetic CABG patients in whom great saphenous vein was used as a conduit. Materials and Methods: It was a cross sectional study on 60 patients who underwent CABG during July 2003 to June 2005 in department of cardiovascular surgery, National Institute of Cardiovascular Diseases (NICVD). Results: The age in group A (Diabetic) ranged from 40-72 years in group B (Non Diabetic) the age range was 40-65 years. Myocardial infarction and Congestive cardiac failure were the predominant risk factors in both age groups. There was no motor or sensory disturbances post operatively. Some patients developed swelling, tenderness, paresthesia in both group but it was not statistically significant. Conclusion: Morbidity occurs in both diabetic and non diabetic patients with certain complications like numbness, paresthesia, swelling etc. at the harvesting site.
